You can configure the number of retries (retry count) and the duration of wait time between the retries (retry interval) using the following registry keys:
Key: HKLM\System\CurrentControlSet\Services\OnCommandHyperV\Parameters DWORD value in seconds: vss_retry_sleep (The time duration to wait between retries) DWORD value: vss_retry (Number of retries)
These settings are at the Hyper-V host level and the keys and values should be set on the Hyper-V host for each virtual machine. If the virtual machine is clustered, the keys should be set on each node in the cluster.
You must restart SnapManager for Hyper-V after making changes to or adding these registry keys.
